What is an epoxy blob?
The blob is an epoxy resin to protect the IC with the bonding mechanically; the bonding wires are very thin (as thin as 10μm for gold wire) and therefore extremely fragile. Another form of protection it offers is reverse engineering protection.
How do you make a blob painting?
Once the paint is dry, apply paint and medium previously mixed together. The blobs will vary in sizes. With a fine detail brush, feel free to link some blobs to create atoms of two or three blobs. Let them dry fully for 10 to 24 hours depending of the quantity of the paint applied and the thickness of the blob.
Why are chips covered in epoxy?
In all cases, the chip and connections are covered with an encapsulant to reduce entry of moisture or corrosive gases to the chip, to protect the wire bonds or tape leads from physical damage, and to help dissipate heat.
How do you remove epoxy blob?
Use a small utility knife to periodically scrape at the epoxy as you heat it. Eventually it will start to soften, and you’ll be able to gently scrape it free little by little. This can be very slow going, as the epoxy used is often extremely durable and strong.
What is color blob technique?
Blob Art is a still young painting technique that involves applying acrylic paint to a canvas in so-called blobs or round, even “spots of paint” and layering them on top of each other one after the other between several drying phases.
What is color blob?
Blobs are sections of the visual cortex where groups of neurons that are sensitive to color assemble in cylindrical shapes. They were first identified in 1979 by Margaret Wong-Riley when she used a cytochrome oxidase stain, from which they get their name. Blobs are on the parvocellular pathway.
How do I decap an IC?
There are a few different ways to decap a chip, but the most common method utilizes chemicals like nitric acid, sulfuric acid, and acetone to essentially melt the epoxy right off the top of the chip, then neutralize the acid so it’s safe to examine.
What is the black blob on circuit boards?
The black blob is the main IC of the device. Many devices use COB or chip-on-board to reduce the cost of components and manufacturing.
What color code is black?

What kind of glue do you use for blob art?
Just make sure that the colors are not too thin or too thick. The middle way is quite suitable for Blob Painting. You need the Deco Varnish to dilute the acrylic paints. First you mix the Deco Varnish and acrylic paint. Then add the vinyl glue. For these three ingredients I use a mixing ratio of 1:1:1.
How to make a blob of acrylic paint?
You need the Deco Varnish to dilute the acrylic paints. First you mix the Deco Varnish and acrylic paint. Then add the vinyl glue. For these three ingredients I use a mixing ratio of 1:1:1. For a 8 oz bottle I recommend 80 g of each component. Stir everything well together again and then pour the mixture into the 8 oz squeeze bottles.
How to make blob shapes in blobmaker?
Blobmaker makes it easy to create unique blob shapes based on random data. Modify the complexity (number of points) and contrast (difference between points) to create different types of organic svg shapes. Press that dice button until you find a blob you like and download it as an SVG or copy the code directly to your clipboard.
Who is the artist who invented the Blob?
The artist who revolutionized Blob Painting is called Mike Hammer, born and raised in Calgary, Toronto. He is well known in the artist scene. Now I would like to make a contribution to bring this wonderful technique a little closer to you. I will give you information about how you can create your own unique artwork step by step.
